Abstract: A one-way glass with switching modes includes an absorbing layer located on a weak light side, a reflecting layer located on an intense light side, and a converting layer stacked between the absorbing layer and the reflecting layer. The absorbing layer absorbs first polarized light and allows second polarized light to pass through. The reflecting layer reflects the first polarized light and allows the second polarized light to pass through. Unpolarized light incident from the weak light side or from the intense light side is respectively converted into the polarized light. During the process of gradually adjusting the converting layer from a twisted state to a vertical state, rotated angles of polarization directions of the first polarized light and the second polarized light gradually decrease.

Abstract: A switchable grating and an application thereof are provided. The switchable grating includes two electrically conductive substrates and a switchable liquid crystal grating layer, which is disposed between the two electrically conductive substrates. When an electric field is applied to a presumption area of the switchable liquid crystal grating layer by the two electrically conductive substrates, the electric field could shift an orientation of a cholesteric liquid crystal molecule of the presumption area. When the electric field is removed, the cholesteric liquid crystal molecule still maintains the aforementioned orientation, thus decreasing energy consumption. When a display device manufactured by the aforementioned switchable grating switches an image to a 2D image or a 3D image, the display device has lower energy consumption.
